Hi, I'm new to LDD, and until I learn my way around, I was just recreating some of my 'real' models from the instructions. I was trying to recreate the mini Tantive IV that comes with the UCS Star Destroyer (which I don't have by the way!) but found the following problem: If I place piece 4733 (Brick 1x1 w/ 4 knobs) directly next to part 6541 (Technic Brick 1x1) - which is required to make the backbone of the ship - then try to move the two items together (or any combo thereof) - LDD crashes immediately. I have tried this several times and always get the same result. Is anyone else getting this? This is the first problem I have encountered within LDD so far, but it might be something I'm doing wrong(?) I'm currently using LDD 4.2.5 (brickset 604.1) on an ageing Sony Vaio laptop with a Pentium M750 processor, 1Gb RAM and an NVIDIA GeForce 6200 GPU. Thanks for any advice you can give!
